To all. whom) it truly ooncern:

State of-Mi'ssou'ri, have intented certain new and useful Improvements in Thermostatlc Air-ltegulators; and I do declare;the;f0l-

' lowingto be a full,-' clear, and exact'descriptibri' of the invention, 1 such as will enable othersski'lled in. the art to which it appertains t0 make-and use the same,- reference being, had to the'accompanying drawings,-

and to; the letters and figures of. reference marked thereon, which form a part -of this specification.- I

in enti-on relates to thermostatic-air regulators .for carbureters', and more parv ticularly to a devlce of this character, which maybe located between the carbureter and.

the intake'manifold of an internal'combustion engine; theprincl pal object'of the device being to providea -reg'ulatoroffthis character, which may be quickly. attachedto. v

The above mechanism operates proportemperature causes the thermostat to expandand lower the plug 22, thereby increas-Q mg the area of the aperture 23 and supplying a greater amount of air to the intake manifold to maintain a uniform fuel mixture. i

Having thus described my invention, what I claim as new therein, and desire to secure by Letters-Patent, is:

Claims: i

1. The combination with an airdistribut ing member, ofa housing having its" interior I m communication with sa dmember, an

a thermostatic arch within the housing, and a tapered plug on said arch projected into said aperture. I

a The combination with anrair distribut'' ing chamber, of a housing having an inteand a tapered plug on said member pro The combination with a. air'diStribut ing chamber, of a housinghaving an inte- 50. for registrationswith the car vrior chamber in communication .with -the distributing chamber, \a flexible diaphragm closing the housing and having a central aperture therein, a thermostatic'al'ch vwithin I thehousing chamber, and a 'tapered plug. mounted on said arch'and projected through the aperture in said diaphragm, for" the pur- I, u

pose set forth;

4. The combination with 'a motor having an i intake manifold anda -.carbureter, of-a device for introducing air into said mani-' fold. comprisinga flat head having an. inte-- rior chamber and a central apprture adapted ureter and in jected'through the aperture in said dia take. manifold, having a plurality of apertures opening from said interior chamber into said central aperture, "a cylindrical" member, integral with' said flat head and having achamber communicating with the interior chamber in said head, a tapered plug supported in-the cylindrical member,-

and a flexible diaphragm fixed in said cylindrical member, and having ia central aperture surrounding and spaced from said plug; the's'aid diaphragm being adapted for movement by absolute-pressure in the intake manlfold for changing the relative positions,

of said diaphragmaperture and said tapered tween.

- into sa1d' central aperture, ii -cylindrical member integral with said f flat head and having a chamber communicating'with the interior chamber in said head, a thermostat- -rior chamber communicating with the dis- .tributing chamber,.-a flexible diaphragm on -said housing having a central aperture there! in, "a thermostatic member in said housing in said chamber comprising a plurality of so that variation in temperature .will' change -'the height-of said-arched, units, a tapered plug on said thermostat,'-and a flexible diaphragm rigidly secured-insaid cylindrical "member and having: a central aperture .sur-

rounding; and spaced .fromsaid tapered plug, w ereby variations in the absolute arched units consisting of metal strips have ting difierent' expansion coefficients arranged the area'of the spa ce therebetween, irrespec:
